Don’t let anybody tell you how often to wash your hair. How often you wash your hair is a personal decision—one that depends on your hair type, hairstyle, and lifestyle (for example, how often you go to the gym or the climate in which you live). Keeping your hair clean and protected from damage is important, so using the proper shampoo and conditioner for your hair is key, regardless of how frequently you wash your hair. If you have color-treated hair, for example, it is important to use a mild shampoo, followed by conditioner, which provides crucial protection for fragile hair. Today’s shampoos and conditioners are formulated to actually improve the condition of hair, even with daily use, so if you wash your hair frequently, it’s not a bad thing.
